• Authors: Rania Briq, Chuhang Zou, Leonid Pishchulin, Chris Broaddus, Juergen Gall
• Abstract summary: We consider the problem of synthesizing multi-action human motion sequences of arbitrary lengths. Existing approaches have mastered motion sequence generation in single-action scenarios, but fail to generalize to multi-action and arbitrary-length sequences. We propose a novel efficient approach that leverages the richness of Recurrent Transformers and generative richness of conditional Variational Autoencoders.

• Abstract: We consider the problem of synthesizing multi-action human motion sequences of arbitrary lengths. Existing approaches have mastered motion sequence generation in single-action scenarios, but fail to generalize to multi-action and arbitrary-length sequences. We fill this gap by proposing a novel efficient approach that leverages the expressiveness of Recurrent Transformers and generative richness of conditional Variational Autoencoders. The proposed iterative approach is able to generate smooth and realistic human motion sequences with an arbitrary number of actions and frames while doing so in linear space and time. We train and evaluate the proposed approach on PROX dataset which we augment with ground-truth action labels. Experimental evaluation shows significant improvements in FID score and semantic consistency metrics compared to the state-of-the-art.

  Existing algorithms directly generate the full sequence which is expensive and prone to errors. We propose KeyMotion, that generates plausible human motion sequences corresponding to input text. We use a Variationalcoder (VAE) with Kullback-Leibler regularization to project the Autoencoder into a latent space. For the reverse diffusion, we propose a novel Parallel Skip Transformer that performs cross-modal attention between the design latents and text condition.

  Text-to-motion generation has gained increasing attention, but most existing methods are limited to generating short-term motions. We propose a novel approach that utilizes a past-conditioned diffusion model with two optional coherent sampling methods. Our proposed method is capable of generating compositional and coherent long-term 3D human motions controlled by a user-instructed long text stream.

  We propose an action-conditional human motion generation method using variational implicit neural representations (INR) Our method offers variable-length sequence generation by construction because a part of INR is optimized for a whole sequence of arbitrary length with temporal embeddings. We show that variable-length motions generated by our method are better than fixed-length motions generated by the state-of-the-art method in terms of realism and diversity.

  We tackle the problem of action-conditioned generation of realistic and diverse human motion sequences.

We learn an action-aware latent representation for human motions by training a generative variational autoencoder.
